I was on TRT for years and now switched to just 50mgs of test cyp per week, small 1/2 ml shot into the shoulder very easy. Keeping doses low and safe. I'm 58 5'11 around 180. My goal is to get leaner and look younger is it ok to add 100mgs of primobolan per week? 1 ml ampule shot. I want to add the primo but not sure if its effective at this low 100mgs dose.
